#A3F210 Hex Color

Pair #a3f210 with charcoal, navy, or black to ground its electric brightness; muted sage and soft gray can add contrast without competing, while deep purple creates a more dramatic direction. Keep the lime as an accent for a calmer, balanced palette.

Use black text on #a3f210 for strong readability: the color has a reported contrast ratio of about 15.3:1 with black, while white text is much weaker for most interface contexts. Its intense brightness also makes it more effective for buttons, icons, highlights, and small accent areas than full backgrounds.

#a3f210 reads as a cool-leaning lime because its vivid green component outweighs its yellow cast, though its high brightness keeps the shade energetic rather than icy or muted. That balance suits active, youthful visuals more than quiet, traditional palettes.
